The aim was simple: to pedal to the furthest point in each of Europe, Asia, and Africa. He didn’t train or plan. He just started.

A born naturalist and a fearless traveler, Vladimir Dinets wrote travel guides, conducted field research, and lived a couple of lives before he was accepted into the PhD program in zoology at the University of Miami.

Boyd Varty had an unconventional upbringing. He grew up on Londolozi Game Reserve in South Africa, a place where man and nature strive for balance, where perils exist alongside wonders. Founded more than 80 years ago as a hunting ground, Londolozi was transformed into a nature reserve beginning in 1973 by Varty’s father and uncle, visionaries of the restoration movement.

Early in 2013 Neil Hayward was at a crossroads. He didn't want to open a bakery or whatever else executives do when they quit a lucrative but unfulfilling job. He didn't want to think about his failed relationship with 'the one' or his potential for ruining a new relationship with 'the next one'.
